IMPROVEM ENT IN WOOD-COMPRESSORS.

Specification forming part of Letters Patent No. 143,243, dated September 30, 1873; 'application filed CASE D.

through my compressor. Fig. 2 is an end view ofthe same.

Similar letters of reference indicate corresponding parts in both gures.

'lhe object of this invention is to compress kinding-wood and other substances preparatory to applying bands or cords around the same, so that when the bundles are allowed to expand by freeing them from the compression they will be very tightly bound, as will be hereinafter explained.

Prior to the invention which I shall hereinafter explain kindling-wood has been pushed through a tube, which consisted of two right cylinders, connected by an annular beveled shoulder, which allows the wood to be forced from a larger cylinder into and through a smaller cylinder, thus holding the charges of wood in a condition for applying bands around them. Such a contrivance does not tightly compress the bundles, and is only designed for conveniently holding them in uniform quantities to be bound.

rEhe following description will enable others skilled in the art to understand my compressor.

Through this device I form a chamber, Af, which is tapered from end to end, and which does not present an abrupt shoulder or other obstruction. The length of the chamber A is such that when it is once lled the introduction into it thereafter of a charge will properly expose beyond its smallest end a portion of a charge to be bound-v-for instance, the chamber A may be equal in length to the length of two charges and a half, as shown in Fig. 1. The diameter of the largest end of the chamber A is about equal to theamount of material which it is desired to compress into a bundle, and the smallest end of this chamber is equal in diameter to the degree of compression ywhich it is desired to give a bundle in order to bind it, and have it properly tight after it is allowed to expand.

I do not claim under this petition means for binding the bundles, nor meansfor pressing` them into and through the tapered chamber; but I prefer to employ for such purposes the devices described in my applications for Letters Patent marked, respectively, Cases B and C, and bearing even date with the tiling of.

this.

It will be seen from the above description that the tapered chamber A will gradually compress the material from circumference to center as it isrmoved from the feed to the discharge end of this chamber. This compression is continuous throughout the length of the chamber; consequently the pressing device and its operating parts will not be subjected to sudden and injurious shock, which they would receive in the double cylindrical tube to which I have above referred.

By constructing the chamber A with a considerable degree of taper, as shown inFig. l, I do not have to employ cutters at its feeding end for trimming and rounding the charges, as they are comparatively loose at first, after which they are compressed, as above described.

Having described my invention, whatI claim as new, and desire to secure by Letters Patent, 1s-

YThe compressing chamber A', presenting a taper which is uninterrupted from one end to the other, as herein shown and described.
